TablePattern.TablePatternInformation.GetRowHeaders 메서드

정의

네임스페이스:

System.Windows.Automation

어셈블리:

UIAutomationClient.dll

테이블의 모든 행 머리글을 나타내는 AutomationElement 컬렉션을 검색합니다.

public:
 cli::array <System::Windows::Automation::AutomationElement ^> ^ GetRowHeaders();

public System.Windows.Automation.AutomationElement[] GetRowHeaders ();

member this.GetRowHeaders : unit -> System.Windows.Automation.AutomationElement[]

Public Function GetRowHeaders () As AutomationElement()

반환

AutomationElement[]

AutomationElement의 컬렉션입니다. 기본값은 빈 배열입니다.

예제

다음 예제에서는 특정 테이블 항목에 대 한 행 또는 열 헤더를 검색 합니다.

이 예제에서는 간의 관계를 위해는 RowOrColumnMajor 속성 행 및 열 머리글 항목에 대해서는 설명 합니다. 그러나 테이블 행 및 열 머리글에 관계 없이 있습니다를 RowOrColumnMajor 테이블의 속성입니다.
